grandmother of eight who was about to receive an undergraduate degree; clearly, she was still in college, despite having been born in 1938. Admittedly, I do not know when (or if) she moved to Ann Arbor.
You may want to spend some time on your logic skills, as well as your math skills.

Pivot tables are great for comparing two independent variables, but I can't get my brain to figure out a pivot with three DEPENDENT variables and compare them over time. Maybe it can be done, but I stared at the pivot table all day and couldn't come up with a valid solution.

Variables w distinct categories could be ordered (say, smallest =1; largest = 7) or not (say, 7 different locations). In the first case, I can see what nonlinear might mean; but not in the 2nd case. So, a good response would require more info about the problem.

<br>Look up Prof Brown's email at the bschool; I bet she could help not that I know her personally nudge nudge wink wink.

Appreciate your help. in this case those categories do increase as you go "up", but one increases as a step function, the other as a non-linear function (think asymptotic)

<br>909dewey up above is in the same industry as me, so I think he might be my best bet. If we can't figure it out, maybe I will look for this prof you mention.

<br>Thanks again, let's go back to sports now.
